In this article, we will learn how to read the co-ordinates of a point drawn on the graph. A graph consists of four parts called the four quadrants. The horizontal line in the middle of the graph is called the x-axis. The vertical line drawn in the middle of the graph is called the y-axis. Let us look at an example. Consider the point drawn on the graph below.
We read the graph points as follows:
Step 1:
Draw a vertical line from the point to the x-axis. The point where the line meets the x-axis is the x-coordinate of the point. The x-coordinate of the point in our example is 2.
Step 2:
Draw a vertical line from the point to the y-axis. The point where the line meets the y-axis is the y-coordinate of the point. The y-coordinate of the point in our example is 3.
Step 3:
The coordinates of the point as given as (x,y). In our example the coordinates of the point are (2,3). This can be seen in the image below.
Example 2:
Let us look at another example. Consider the point in the image below.
Following the three steps explained above we see that the coordinates of the point are (-4,-3)
